FURRING- AND FAS'JJIELATIJRTG? STRIP.

Application filed October 16, 1922. Serial No. 594,678.

To all whoma't may concern:

Be it known that I, THEODORE J. O'rro, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Furring and Fastening Strip, of which the following is a specification.

This invention relates to improvements in devices for the furring of walls, ceilings and surfaces, and in particular to such a device in the form of a metallic strip adapted to use with wire lathing, the combination forming the anchoring or foundation means to receive and support a plaster or cement coating for walls or the like.

The present common method of anchoring plaster to the exterior walls of bungalows and buildings, is by laying wire mesh lathing over vertically positioned wooden furring strips, spaced about eight inches apart and nailed over building paper to the sheathing of the building. Plaster is then spread over the wall surface, and the wooden furring strips bedded in the wet plaster soon As the plaster dries, the strips shrink more or less, thus, unequal stresses are set up in the wall, resulting, upon close examination in fine hairlike cracks throughout the wall. These cracks tend to become longer and wider as the annual seasonal changes take place, and eventually patches of plaster drop off.

The main object of my invention is to' overcome the above initial fine cracks, and.

thus extend the life of the wall to a very marked degree and present a uniform and continuous surface. Other important objects of the furring strip are, the quick application of it to the sheathing and building paper, and its efiective holding power, its uniform outstanding distance from the sheathing surface, and the ease of application of the wire lathing over and to the bearing surface of the strips, and the fastening thereto.

In carrying out my invention, I take a strip of material, preferably sheet-metal, and roll or otherwise form it into an angular shape, more or less convex on one side and concave on the other, and have tongues or spurs struck up therefrom, on which the wire fabric may hang and be fastened. At each end of the strip I provide a fiat portion,

' and perforate the same to receive a fastening nail. I then turn over on itself the extreme end of said portion to cover the head of the nail and retain the latter as a part of the article, and in position to drive into the basic support to fasten the strip in place.

Other features and objects of the invention than those enumerated, will appear hereinafter.

In the accompanying sheet of drawings, I have illustrated the invention, both by itself and attached to a wall and supporting a section of wire fabric, and a section of plaster. 4

Figure 1 is a plan view of my strip.

Figure 2 is a sectional elevation with a furring strip secured to the sheathing, and with building paper therebetween and a portion of wire fabric hung and secured to the strip.

Figure 3 is a face view of a wall showing various stages of construction.

Figure 4 is a cross-section of a strip on the line AA of Figure 1.

Referring to the drawing and the figures thereof;the sheathing of a wall is represented by the numeral 1, the studding being omitted as unnecessary in this connection. Upon the sheathing is the building or other protective paper 2, and secured thereto by the furring strips 3. The latter are fastened by nails 4 projecting from flat portions at each end of the strip as at 5, the nails being previously positioned therein to constitute a part of the unit strip. The end of the strip covering the head of the nail as at 6, retains the nail in place and provides for the blow of a hammer to fasten the article to the sheathing.

On the ridge of the furring strip are struck up spurs or tongues 7 onto which the wire fabric 8 is hung, after the furring is in place. The wire being positioned, engaging one or more spurs, the end of said spur may be turned down over the wire strand, as shown more particularly at 9 in Figure 2. It will be noted that half of the spurs 7 point in one direction and the remaining half in the other, the object being that the mechanic, can fasten the strips to the wall or other support, without stopping to look whether one end or the other is up. The spurs may be slightly notched as at 10, thereby providing a snaplock for the wire before the spur is hammered down.

If desired, the sides of the strip 3 may be notched or cut away as at 11, to aflord additional plaster hold. The end 6 of the flat end of the strip, being turned over the nail head, also affords additional plaster hold.

In practice, the strips are completely formed and with the nails in place, and are furnished to the workmen as complete articles.

In Figure 3, I have shown at 2 the building paper, the joints of the sheathing showing in dotted lines. Some fur-ring strips are shown in place with wire fabric thereon, and at 12 is the finishing coat of plaster applied to the Wall.

Having thus illustrated and described my invention in its preferred form, I wish it understood that the same may be modified section and spurs struck up therefrom, said spurs facing in opposed directions, and said strip having fiat portions adapted to hold nails and furtherfla-t portions turned over the heads of said nails.

2. As a new article of manufacture, a furring strip having a concavo-convex crosssection and spurs struck up from the crown thereof, said spurs facing in opposed directions and said strips having nails secured thereto, said nails projecting through fiat portions and forming a part of the article, and retained thereto by portions of the strip turned over the nail heads.

3. As a new article of manufacture, a sheet-metal fur-ring strip of angular crosssection, having spurs struck up from its ridge in opposed directions and having flat ends engaging and holding nails as a part of said article.

In testimony whereof I affix my signature.

THEODORE J. OTTO.
